I'm sure it's been done before but hot glue would be my last choice to use for a build. #1 because of the excessive weight. #2 because of its lack of penetration into the wood. Luckily the covering is ultimately what will "squeeze" all the parts tightly together. I doubt the hot glue adds very little structural strength though.
I've had a few fuselage builds that fit together so well without glue that I
momentarily considered covering them with out gluing them together. Common sense won out though.
